- A
Enable public network access from all networks for ease of use
Why wrong: Increases attack surface
- B
Use access control lists (ACLs) to restrict access to specific directories
Granular permissions
- C
Allow anonymous access to enable sharing
Why wrong: Anonymous access is not secure
- D
Disable soft delete to prevent accidental retention of deleted data
Why wrong: Soft delete enhances security by allowing recovery
- E
Enable encryption at rest using customer-managed keys in Azure Key Vault
Encrypts data at rest

How to Secure Sensitive Data in ADLS Using ACLs and CMK Encryption
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: access Control Lists (ACLs). Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO actions should you take to secure sensitive data in Azure Data Lake Storage Gen2? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use access control lists (ACLs) to restrict access to specific directories
The correct answers are B and E. Option B: Using access control lists (ACLs) in Azure Data Lake Storage Gen2 allows granular permissions at the directory and file level, enabling you to restrict access to sensitive data. Option E: Enabling encryption at rest with customer-managed keys in Azure Key Vault provides an additional layer of security by allowing you to manage your own encryption keys. Option A is incorrect because public network access from all networks exposes data to potential threats; it should be restricted. Option C is incorrect as anonymous access should always be disabled for sensitive data. Option D is incorrect because soft delete should be enabled to protect against accidental data deletion or corruption.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates may confuse access control methods or overlook that customer-managed keys add an extra security layer. They might also assume that disabling soft delete is a security measure, but it actually reduces data protection.

How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Access Control Lists (ACLs)
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
